As you may know, Mapopolis has exited the PDA software business. Thus, we will no longer offer Mapopolis software. You may want to check with Mapopolis to see if they can still offer software directly through them.

I have a Mio 310x`that was purchased / loaded with world maps of several countries and cities. My friend has the 310 Mio. Is it possible to load an SD card with the proper maps of Europe and insert into the csrd slot(friends) and use it successfully? Where does one find these maps please?

Since Mio USA does not offer Europe map at this time, you may want to check Mio's European seller such as Expansys or Amazon UK to purchase Europe map. There is no legal way to purchase Mio Europe map in the US at this time.
